Tony nominee Tom Sturridge (Orphans, "On the Road") will play Henry VI. Hugh Bonneville, who stars in BBC's "Downton Abbey," has been cast as Humphrey, Duke of Gloucester, and Academy Award nominee Sally Hawkins (Mrs. Warren's Profession, "Blue Jasmine") will play his wife Eleanor, Duchess of Gloucester.
